Examples are fans of the traction motors, radiators of the power converters, compressors for compressing gases (eg for generating compressed air for a brake system), a locomotive fire-extinguishing device, electronic devices for controlling the operation of the locomotive, battery chargers, heaters, eg. B. window heating, air conditioners, sockets, lighting devices.

  • z. B. an existing traction intermediate circuit or DC-DC link, are connected to the via a power converter and traction motors, an energy source for the auxiliary system.
  • auxiliary systems in rail vehicles are designed so that they do not have any reference potential. This means that they can operate on a fluctuating electrical potential to vehicle ground or "ground.” If a contact, in particular a short circuit, occurs to vehicle ground, the free-floating state is canceled and the contact point is on vehicle ground However, when further contact with vehicle ground occurs, high short-circuit currents can occur that can destroy system components and also have repercussions on the other parts of the overall electrical system, such as the traction link and the power converters connected to it ,

For example, the time that a phase is turned on during a half cycle of the alternating current is reduced, and / or a time lag of the phase current is created over the undisturbed case.
